Coreopsis &#39;DCORGLOW&#39;

ABSTRACT

A new and distinct  Coreopsis  cultivar named ‘DCORGLOW’ is disclosed, characterized by a compact, radial plant habit and dense branching. Flowers are distinctively light, bright yellow. The new variety is a  Coreopsis , normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Coreopsis grandiflora.

Variety denomination: ‘DCORGLOW’.

BACKGROUND OF THE INVENTION

The new Coreopsis cultivar is a product of a planned breeding programconducted by the inventor, Gavriel Danziger in Moshav Mishmar Hashiva,Israel. The objective of the breeding program was to produce newCoreopsis varieties. The open pollination resulting in this new varietywas made during June of 2011.

The seed parent is the unpatented, propriety variety referred to asCoreopsis ‘CO 11-948’. The pollen parent is unknown as it was an openpollination breeding program. The new variety was discovered in July of2012 by the inventor in a group of seedlings resulting from the 2012crossing, in a greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar ‘DCORGLOW’ was first performedby terminal vegetative cuttings during September of 2012, at agreenhouse in Moshav Mishmar Hashiva, Israel. Subsequent propagation byvegetative cuttings has shown that the unique features of this cultivarare stable and reproduced true to type in more than 20 successivegenerations.

SUMMARY OF THE INVENTION

The cultivar ‘DCORGLOW’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘DCORGLOW’ These characteristics incombination distinguish ‘DCORGLOW’ as a new and distinct Coreopsiscultivar:

-   -   1. Distinctive bright light yellow flower color    -   2. Compact plant habit.    -   3. Very uniform radial plant shape.    -   4. Full, dense plant.

PARENT COMPARISON

Plants of the new cultivar ‘DCORGLOW’ are similar to plants of the seedparent, most horticultural characteristics, however, plants of the newcultivar ‘DCORGLOW’ differ in the following;

-   -   1. Plant habit of the new variety is compact and found, the seed        parent is an upright plant.    -   2. New variety is shorter than the seed parent.    -   3. Plant structure of the new variety is uniformly radial, plant        structure of the seed parent amorphous.    -   4. Larger flowers than the seed parent.    -   5. Shorter peduncles than the seed parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DCORGLOW’ can be compared to the patentedcommercial variety Coreopsis ‘DCOREO16’ U.S. Plant Pat. No. 25,241.These varieties are similar in most horticultural characteristics;however, ‘DCORGLOW’ differs in the following:

-   -   1. The new variety has a lighter yellow flower than this        comparator.    -   2. The new variety has lighter colored foliage than this        comparator.    -   3. Flowers of the new variety are single, flowers of this        comparator are double.    -   4. Peduncles of the new variety are thinner than peduncles of        this comparator.

Plants of the new cultivar ‘DCORGLOW’ can also be compared to thepatented commercial variety Coreopsis ‘Galaxy’ U.S. Plant Pat. No.21,999. These varieties are similar in most horticulturalcharacteristics; however, ‘DCORGLOW’ differs in the following:

-   -   1. Flowers of the new variety are single, flowers of this        comparator are semi-double.    -   2. Flower color of the new variety is solid light yellow, flower        color of this comparator is a blend of yellow and darker yellow.    -   3. Plant height of the new variety is 20 to 25 cm, this        comparator plant height is 25 to 30 cm.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color atypical plant of ‘DCORGLOW’ grown in 12 cm pots outdoors in MoshavMishmar Hashiva, Israel.

FIG. 2 illustrates in full color multiple typical inflorescence of‘DCORGLOW’. Age of the plant photographed is approximately 11 weeks froma rooted cutting in a 12 cm pot. The photographs were taken usingconventional techniques and although colors may appear different fromactual colors due to light reflectance it is as accurate as possible byconventional photographic techniques.
